Description

Technical Field

[0001] The invention belongs to the technical field of ore sample processing, and particularly relates to an ore sample mixing device. Background Art

[0002] When preparing samples for mineral grinding experiments, workers need to mix them thoroughly. Currently, this is done manually, where workers place the sample into a mixing bag, then shake the bag with both hands to evenly distribute the sample. The degree of mixing uniformity depends on the worker's responsibility and skill.

[0003] Furthermore, after mixing, workers need to open the mixing bag and pour the sample into a sample pan. This operation easily generates dust, which can lead to excessive PM2.5 exposure for workers and cause environmental pollution. Long-term exposure to this environment poses a health risk. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention aims to provide a device for mixing ore samples.

[0005] In order to achieve the above technical objectives, the technical solutions adopted by the present invention are as follows:

[0006] A mineral sample mixing device comprises a container for containing the mineral sample and an air knife assembly located inside the container for mixing the mineral sample;

[0007] The container is provided with a feed end and a discharge end, the feed end has two states: closed and open, and the discharge end has two states: cut-off and conducting;

[0008] The air knife assembly performs rotational motion under the drive of a rotational power source, and the air knife assembly delivers pressurized gas under the drive of the gas source.

[0009] In the present invention, when the ore sample needs to be placed in the container, the feed end is opened and the discharge end is closed. When a mixing operation is required, the feed end is closed and the discharge end is closed, thereby improving the airtightness and preventing the ore sample from escaping from the upper side, polluting the environment, and endangering the health of the workers. When the ore sample needs to be discharged, the feed end is closed and the discharge end is connected.

[0010] The mixing action is constrained inside the container and is automatically implemented by the air knife assembly under the drive of the rotary power source and the air source. The mixing quality can be effectively guaranteed and the labor intensity of the staff is reduced. Specifically, the rotary power source drives the air knife assembly to rotate, and the rotation of the air knife assembly can promote the dispersion and mixing of the ore sample. The rotary power source selects a motor, and the control of the motor is relatively simple. The speed of the motor can be set as needed to adjust the speed of the air knife assembly. The air source provides pressurized gas to the air knife assembly, and the pressurized gas is discharged through the air holes on the air knife assembly to impact the ore sample in the container to improve the mixing effect. These two mixing methods are collectively called pneumatic mixing.

[0011] The beneficial effects of the present invention are as follows: when performing sample delivery and mixing operations, the feed end is closed and the discharge end is cut off to ensure airtightness, thereby preventing the mineral sample from escaping from the upper side, polluting the environment, and endangering the health of the workers; when the mineral sample needs to be released, the feed end is closed and the discharge end is connected, and the dust suppression hood regulates the dust in a limited space to prevent the dust from polluting the external environment; when mixing is performed, the mixing action is constrained inside the container and is automatically implemented by the air knife assembly under the drive of the rotating power source and the air source, so that the mixing quality can be effectively guaranteed and the labor intensity of the workers is reduced.

[0035] The technical solutions of the present invention are described in detail below in conjunction with specific embodiments and their accompanying drawings. The embodiments described herein are specific embodiments of the present invention and are used to illustrate the concept of the present invention; these descriptions are explanatory and exemplary and should not be understood as limiting the embodiments of the present invention and the scope of protection of the present invention. In addition to the embodiments described herein, those skilled in the art can also adopt other obvious technical solutions based on the contents disclosed in the claims of this application and its specification, including technical solutions that adopt any obvious replacements and modifications to the embodiments described herein.

[0036] Example 1

[0037] like Figure 1 、 3 As shown, this embodiment provides a mineral sample mixing device, comprising a container 11 for containing the mineral sample and an air knife assembly 12 located inside the container 11 for mixing the mineral sample;

[0038] The container 11 is provided with a feed end 112 and a discharge end 113. The feed end 112 has two states: closed and open. The discharge end 113 has two states: cut-off and conducting.

[0039] The air knife assembly 12 rotates under the drive of the rotary power source, and the air knife assembly 12 delivers pressurized gas under the drive of the gas source.

[0040] In this embodiment, when the ore sample needs to be placed in the container 11, the feed end 112 is opened and the discharge end 113 is closed. When a mixing operation is required, the feed end 112 is closed and the discharge end 113 is closed, thereby improving the airtightness and preventing the ore sample from escaping from the upper side, polluting the environment, and endangering the health of the workers. When the ore sample needs to be discharged, the feed end 112 is closed and the discharge end 113 is connected.

[0041] The mixing action is constrained inside the container 11 and is automatically implemented by the air knife assembly 12 under the drive of the rotary power source and the air source. The mixing quality can be effectively guaranteed and the labor intensity of the staff is reduced. Specifically, the rotary power source drives the air knife assembly 12 to rotate. The rotation of the air knife assembly 12 can promote the dispersion and mixing of the ore sample. The rotary power source selects a motor. The control of the motor is relatively simple. The speed of the motor can be set as needed to adjust the speed of the air knife assembly 12. The air source provides pressurized gas to the air knife assembly 12. The pressurized gas is discharged through the air holes on the air knife assembly 12 to impact the ore sample in the container 11 to improve the mixing effect. These two mixing methods are collectively called pneumatic mixing, and the air source can be provided by an air compressor.

[0042] Example 2

[0043] like Figure 1 、 4 As shown in Figures 5, 6 and 7, this embodiment provides a mineral sample mixing device, which is different from Example 1 in that it includes a feeding spoon 14 and an end cover 13 adapted to the feed end 112. When the end cover 13 is separated from the feed end 112, the feed end 112 is in an open state. When the end cover 13 is attached to the feed end 112, the feed end 112 is in a closed state.

[0044] The feeding spoon 14 is provided with a spoon body 141 for accommodating the mineral sample, and a first axis 144 and a second axis 142 are distributed on the outer surface of the spoon body 141. The first axis 144 and the second axis 142 are on the same straight line, and the first axis 144 and the second axis 142 are spaced 180 degrees apart.

[0045] A handle 145 is provided on the outer surface of the first shaft 144;

[0046] The end of the second shaft 142 is provided with a limit joint 143;

[0047] The feed end 112 is funnel-shaped and is provided with two relatively distributed slots 1121. The bottom of the slot 1121 is arc-shaped and adapted to the first shaft 144 and the second shaft 142. The end cover 13 is provided with a cover body 131, a gripping body 132 located on one side surface of the cover body 131, and two plug blocks 133 located on the other side of the cover body 131. The end face of the plug block 133 is arc-shaped and adapted to the first shaft 144 and the second shaft 142. The plug block 133 and the slot 1121 cooperate with each other to form a through hole for passing the first shaft 144 and the second shaft 142.

[0048] In this embodiment, the function of the end cover 13 is to close and open the feeding end 112. The spoon body 141 in the feeding spoon 14 is used to accommodate the ore sample. After the ore sample is placed, the first shaft 144 and the second shaft 142 of the feeding spoon 14 are inserted into the slot 1121 of the feeding end 112. Then, the end cover 13 is placed at the feeding end 112, and the insert block 133 of the end cover 13 is inserted into the slot 1121. The insert block 133 and the slot 1121 cooperate with each other to form a through hole that just accommodates the first shaft 144 and the second shaft 142. At this time, the first shaft 144 and the second shaft 142 exist at the through hole, completing the full closure, greatly improving the airtightness during sample feeding, and preventing dust from escaping from the upper side during feeding.

[0049] Since the outer surface of the first shaft 144 is provided with a handle 145, the handle 145 has two functions. Function 1 is to indicate the circumferential posture of the feeding spoon 14. When the handle 145 is at the bottom, the spoon body 141 is in a holding posture. When the handle 145 is at the top, it indicates that the feeding spoon 14 has rotated and the spoon body 141 has poured the ore sample. Function 2 is to facilitate the staff to hold and apply force to rotate the feeding spoon 14. The staff can hold the handle 145 and rotate and shake it repeatedly to shake off all the ore samples from the spoon body 141.

[0050] The funnel-shaped feed end 112 has a converging effect;

[0051] The function of the limiting joint 143 is to prevent the feeding spoon 14 from falling off along the axial direction.

[0052] Example 3

[0053] like Figure 1 、 9As shown, this embodiment provides a mineral sample mixing device, which differs from Example 1 in that it includes a cleaning system 15, the cleaning system 15 includes an air compressor 151, a cleaning nozzle 154, a first air path 152 connecting the air compressor 151 and the cleaning nozzle 154, a first electrically controlled valve 153 located on the first air path 152, and the cleaning nozzle 154 is installed on the container 11 and extends into the interior of the container 11.

[0054] In this embodiment, the cleaning system 15 is used to blow off the mineral samples adhered to the inner wall of the container 11. Specifically, the air compressor 151 pressurizes the air, and the pressurized gas is transported to the cleaning nozzle 154 through the first air path 152. The cleaning nozzle 154 releases the pressurized gas. After the pressurized gas escapes, it hits the inner wall of the container 11, impacting the adhered mineral samples and causing them to fall off. The first electrically controlled valve 153 is used to control the on-off of the first air path 152.

[0055] In some optional instances, multiple first gas paths 152 can be provided, and multiple cleaning nozzles 154 can be provided and dispersedly arranged on the container 11. Each first gas path 152 corresponds to a cleaning nozzle 154. Cleaning nozzles 154 at different positions are responsible for cleaning tasks in different areas. By controlling the on and off of the first electric-controlled valve 153, the cleaning nozzles 154 on different first gas paths 152 can obtain pressurized gas intermittently, avoiding simultaneous pressurized gas acquisition that causes gas to impact each other and weaken the effect.

[0056] Example 4

[0057] like Figure 1 、 3 As shown in FIG. 10 , this embodiment provides an ore sample mixing device. The difference from the embodiment 1 is that the discharge end 113 is in the shape of a thin tube and a valve 17 is installed at the discharge end 113. The valve 17 controls the cut-off and conduction states of the discharge end 113.

[0058] The discharge end 113 is radially provided with a branch pipe 111 below the valve 17. The branch pipe 111 is connected to the recovery system 16. The recovery system 16 includes a suction fan 165 and a second air path 161. A second electric-controlled valve 162 and a discarded sample box 163 are arranged on the path of the second air path 161. One end of the second air path 161 is connected to the branch pipe 111, and the other end is connected to the suction fan 165. An air filter cartridge 164 is arranged at the outlet of the discarded sample box 163.

[0059] In this embodiment, the discharge end 113 is in the shape of a thin tube and can control the flow rate of the discharged mineral sample to avoid the generation of large dust by discharging a large amount of mineral sample at once. The valve 17 is used to control the cut-off and conduction states of the discharge end 113. The recovery system 16 is used to recover the mineral sample adhering to the container 11.

[0060] Specifically, the suction fan 165 generates suction wind force. Under the action of suction, the remaining mineral samples enter the sample discard box 163 through the branch pipe 111 and the second air path 161. Under the interception action of the air filter cartridge 164, the air continues to flow outward through the air filter cartridge 164, while the remaining mineral samples remain in the sample discard box 163. The valve 17 is used to control the on and off.

[0061] Example 5

[0062] like Figure 1 、 2 As shown in Figures 8 and 8, this embodiment provides an ore sample mixing device, which differs from Example 1 in that the discharge end 113 is in the shape of a thin tube, the discharge end 113 is slidably connected to the dust suppression cover 19, the lower end of the discharge end 113 is connected to the anti-slip ring 20, the outer ring of the discharge end 113 is sleeved with the spring 18, and the spring 18 contacts the dust suppression cover 19;

[0063] The dust suppression cover 19 is provided with a slip ring 191 , a cover body 193 located at the lower edge of the slip ring 191 , and a lifting handle 192 located at the circumference of the slip ring 191 .

[0064] In this embodiment, the function of the dust suppression cover 19 is to regulate the dust in a limited space to prevent the dust from polluting the external environment. After the ore sample is mixed, it needs to be placed in the sample tray P. Under the action of the spring 18, the dust suppression cover 19 moves down and covers the sample tray P. The cover body 193 of the dust suppression cover 19 and the sample tray P together form a relatively closed space.

[0065] The function of the lifting handle 192 is to hold and apply force when sliding the slip ring 191 up and down. When the staff wants to place the sample plate P under the dust suppression cover 19, they need to move the dust suppression cover 19 upward until the sample plate P reaches the position, and then release the lifting handle 192. The spring 18 applies force to the dust suppression cover 19, so that the dust suppression cover 19 contacts the sample plate P.

[0066] The function of the anti-slip ring 20 is to prevent the dust suppression hood 19 from sliding out from the discharge end and to limit the maximum downward position of the dust suppression hood 19.

[0067] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person skilled in the art without departing from the spirit and technical concepts disclosed herein shall be covered by the claims of the present invention.
